"Quick and automatic"
Auto-defrags at idle, Fast Optimize for better performance, Analyze is very useful. Small RAM use.
Has multi colored Legend but no explanations for symbols. Why can't it also Auto Fast Optimize instead of just Auto Defrag?
Great free utility in an area that has mostly been left to Diskeeper, whose software may be a bit better but has gotten fairly pricey Take a look at Auslogics free Disk Defragmenter too though..
